"Lee Hardy's study of Husserl is an outstanding achievement. The argumentation is crisp and clear throughout, and the discussion of primary and secondary texts is lucid and detailed. Above all, he makes a very good case for an important point that is highly relevant to the current resurgence of interest in phenomenology. Against the tendency of many other interpretations, he shows how Husserl's phenomenology is in principle compatible with a realistic understanding of modern scientific theories."
